If "your" library crashes "my" application, I have no chance to do an
emergency save of the user's data, so presumably that's what Behdad is
getting at.

In the Java bindings, the Gtk-ERROR etc messages that result from these
g_return_if_fail() sanity tests are converted to unchecked Java
Exceptions. This helps enormously with debugging, but the developer can
_also_ do something like:
try {
Gtk.main();
} catch (Throwable t) {
data.emergencySave();
throw t;
}
or such, which means there is at least a chance of attempting to not
lose things.
Whether or not Java's unchecked exceptions is a good idea [or for that
matter whether C programs abruptly terminating on errors] is a topic for
another day :)
